I've used a relational database with a table of nodes (with lat, lon)
and a table of connections (from_node, to_node), then created a view to
represent lines in well-known-text. Move a node and all the lines would
move along with it since they're defined as a view. The line movement
So the solution I am dreaming of is:
1) prepare a point vector layer with all nodes having unique IDs
(e.g. Paris, Madrid, Berlin)
2) have a table where all connecting lines are listed:
LINE_NAME, LINE_START, LINE_END
big tube , Paris, , Berlin

Have you given a look at FlowMapper plugin?
http://plugins.qgis.org/plugins/FlowMapper/
The issue with flowmap is that it's designed for a limited number of flows:
* the matrix must always have the same dimensions as the listed nodes
* the order of matrix and nodes must be the same

Hi,
I'm new to QGIS (long time mapinfo user) - Is it possible to export a
raster to Esri's standard Ascii Grid format?
I'm using QGIS 2.0.1 on a Windows 7 64bit system.
Thanks,

Hi,

Then, a procedure would read the connections from the table and draw
automatically these connecting lines between the nodes.
If you want straight lines between nodes, it is easy. Otherwise you would
have to state rules for making the lines between the nodes, and it can

Thanks Saber,
That seemed to be what I was after but when I exported the Raster to
Arc/Info ASCII Grid format it created a *asc file in a non-text format
which isn't what I was expecting. Seems strange - any ideas?

IIRC there is a bug where you have to correct the command line manually before
running it..
Per default it always creates tiff files (that's why it is a binary file)

Very strange indeed. Just converted one and it appears fine.
Are you sure you picked [GDAL] Arc/Info ASCII Grid and not [GDAL] Arc/Info
Binary Grid?

I follow this thread with interest because I have a layer with exactly
the same behaviour, behaviour which also appear in the transition from
QGIS 1.8 to 2.0.
Unfortunately, I don't find any point with all NULL attributes in this

For all those having trouble with GRASS and Processing - I remember fixing this

If your nodes have origin/destination attribute and a common id for
connecting nodes, I suppose you could use a VIEW, even if it would be
rather inefficient for big number of nodes.
It would work in Spatialite too.
